Become a PHIUS Certified Passive House Builder (CPHB)!

Superinsulation, airtight envelopes, high-performance window installation, site management, component sourcing—passive house construction presents special challenges to builders. The PHIUS CPHB training program prepares construction professionals to meet the passive house challenge.

Instructors bring a wealth of knowledge having built dozens of successful passive house projects. Topics range from design theory and climate-specific detailing to materials, techniques, project management, and quality assurance.

The course offers real-world ins ights into on-site implementation as well as counseling and advice on both the practical and business concerns specific to passive house. The material covers not only craftsmanship, but also risks and liability to the passive house contractor and guidance in both problem-solving and (more importantly) problem avoidance.

Maintaining the PHIUS Certified Builder Credential 

nominal maintenance fee will be billed on a yearly basis starting on January 15, 2018. One listing fee will be due per professional regardless of the number of certified credentials held by that professional. (For example a CPHC® who is also a Certified Builder, will be subject to a single maintenance fee.)

The fee will help maintain and improve the listing database and assist in the development of the continuing education programs for all professionals.

PHIUS Certified Builders can maintain/extend their certification status through either one of the following methods:

1. Build a PHIUS+ Certified Passive Building Project

Successfully building a project within three years after the professional’s certification date will maintain/extend the Builder’s professional credential status by an additional three years.

2. Take and Pass the Current Builder Exam

Successfully completing the Builder exam will maintain/extend the Builder’s professional credential status by three years. Trainees have until 12 calendar months from the conclusion of their specific class to start an exam cycle.

If Builder Certification Expires:

  • A Builder who fails to meet one of the above requirements by their expiration date will be removed from the Builder database and their credential will no longer be considered valid.
  • A Builder whose certification status has expired can reactivate their certification by taking and passing the current Builder exam
